It is true that Exxon has done all it can to melt the tundra, but that does not mean that you can just move Iowa up there and start over again.

But if you take a different approach, and you think of very large scale integration, very advanced materials, very advanced manufacturing so you're pouring chemicals in one end, iPods are spewing out the other and really cool design, that's what we wanted to do.
